Bamboo Crash Barrier on NH-930: Wani to Warora
Published
The first bamboo crash barrier on a National Highway went in on NH-930, between Wani and Warora in Maharashtra, on 3 March 2023. This is what the project authority recorded.
The site
BSU installed 200 m of Kooch Kavach on a straight stretch of NH-930 under NHAI's Chandrapur project unit. The aim was simple: put the barrier on a working highway, leave it to the weather and the traffic, and have the authority report on it.
How it was installed
Kooch Kavach follows the familiar metal beam crash barrier layout, with posts at regular spacing and a continuous beam fixed to them. Because of this, NHAI noted that a contractor who installs metal beam barriers can install it with little change in method. The installation used no concrete, and local workers carried out the work.
What NHAI recorded after three months
NHAI's report of 20 June 2023 recorded three things about the observation period of about three months. There was no weathering of the barrier. There was no theft. No maintenance was needed during the period.
For a first installation on a National Highway, these are the points a highway engineer looks at first. Theft matters because steel barriers are sometimes stolen for scrap value. Weathering matters because a barrier is expected to last years in rain, sun and dust.
What NHAI advised
The report also gave guidance, which BSU follows on every project. Use the barrier first on low to moderate traffic roads. Use trained installers. Compact the posts carefully.
Good guidance from the authority matters as much as good results, because it shapes how the barrier is used on later projects.
Why this trial matters
This 200 m stretch was the first field record for the world's first bamboo crash barrier. It gave other highway agencies something they could see and read about. The longer trials on NH-30, NH-44, NH-09 and NH-48 followed from it. The full sequence is in the Kooch Kavach story.
